Tens of thousands of people, including the president, vice president and top Texas elected officials, are gathering in Dallas later this week for the National Rifle Association’s 147th annual meeting. And protesters will be active throughout.

The convention, which runs through Sunday at the Kay Bailey Hutchison Convention Center in downtown Dallas, comes at an intense moment in the national gun debate. On Feb. 14, a school shooting left 17 dead in Parkland, Florida, sparking student-led protests across the country and calls for gun reform.

Following the school shooting, Dallas Mayor Pro Tem Dwaine Caraway called for America’s largest gun lobby to relocate its meeting, saying it would face “marches and demonstrations.” A Dallas resident launched a petition urging the city to revoke the funds it put toward the NRA convention. It has more than 40,000 signatures.
